Consider a pipeline system. Let the time it takes to process a sub operation in each segment be equal to \( t_p = 20 \, \text{ns} \). Assume that the pipeline has \( k = 4 \) segments and executes \( n = 100 \) tasks in sequence. Consider a non-pipeline system, assume that \( t_n = k t_p \) (a non-pipeline system to perform the operation takes a time equal to \( t_n \) to complete each task), where \( t_p = 20 \, \text{ns} \), \( k = 4 \). Find the speedup of a pipeline processing over an equivalent non-pipeline processing to execute 100 tasks.
